再生空心砌块砌体填充墙-钢管再生混凝土框架骨架曲线模型研究

为研究再生空心砌块砌体填充墙-钢管再生混凝土框架的骨架曲线模型，设计制作了2榀试件并对其进行低周反复加载试验，获取其滞回及骨架曲线。在此基础之上，对试件的骨架曲线模型进行相关的理论分析，建立了再生空心砌块砌体填充墙—钢管再生混凝土框架的四折线骨架曲线模型。研究表明:试件的滞回曲线呈现为饱满的梭形，表现出了良好的抗震耗能性能；通过相关理论分析建立的四折线骨架曲线模型与试验实测骨架曲线吻合良好，可为该类结构在地震作用下的弹塑性地震反应分析提供相关参考。

Study on skeleton curve model of RAC filled steel tube frame with regeneration hollow block masonry wall

To study the skeleton curve model of recycled aggregate concrete (RAC) filled steel tube frame with regeneration hollow block masonry wall, this article designed 2 specimens under cyclic reversed load test. And the hysteretic and skeleton curves were obtained. Based on the foundation, some theories to were used analyze the skeleton curve model of specimens. The four poly-line skeleton curve model of RAC filled steel tube frame with regeneration hollow block masonry wall was built. The results show that the hysteretic curves of specimens present plump spindle shape, and it means the structure has good energy dissipation ability. Based on some theoretic analysis, the four poly-line skeleton curve model of specimens is built and it has good agreement with the test results, and it can provide some reference for the elastic-plastic seismic response analysis of this kind of the structure.
